Answer:
First, you must figure out the equation which should be 12.5=2.5+4x. Then, you subtract 2.5 from 12.5 and you should get 10. So, now the equation is 10=4x that means you now have to divide 10 by 4x. Once you divide, you should be left with the answer 2.5=x. This means that each loaf of risen bread needs 2.5 cups of flower.
